shill: cellular: Obtain IPv4 configuration from bearer.
This CL refactors the cellular code to obtain an IPv4 configuration from
an active bearer object exposed by ModemManager. ModemManager may choose
one of the IP configuration methods: static, DHCP, or PPP. If a static
IP configuration is chosen, shill bypasses DHCP and uses the IP
configuration provided by the bearer. If a PPP configuration method is
choosen, this CL changes the code to bypass DHCP as well.
BUG=chromium:233918
TEST=Tested the following:
1. Build and run unit tests.
2. Verify that shill obtains IP configuration properly under different
bearer configurations: static, DHCP, and PPP.
